It should be noticed that, the two slidingly connecting portions 40 are used for combining the drawer 70 and the frame 10, and there may be lots of connecting manners for connecting the drawer 70 and the two slidingly connecting portions 40, the following description would be focused on the present embodiment.

In this embodiment, the drawer 70 and the two slidingly connecting portions 40 are combined by the two slide rails 80, and the two slide rails 80 are disposed between two sides of the body 71 of the drawer 70 and the two slidingly connecting portions 40. Each of the slide rails 80 includes a fixed member 81 disposed the standing plate 45 of the corresponding slidingly connecting portion 40, and a slide member 83 slidably disposed at the fixed member 81. The two slide members 83 are disposed at a side of the body 71 of the drawer 70, respectively. The bottom plates 47 of the two slidingly connecting portions 40 are located under the corresponding slide rail 80, respectively. The slide member 83 is movable relative to the fixed member 81 with the drawer 70 along an imaginary line L. Referring to FIG. 1, the drawer 70 can move toward the bottom right of the figure and eventually extend out of the electric bed 1. Referring to FIG. 2, the drawer 70 can move toward the left of the figure and eventually move back completely to a position under the second supporting board 37.

Accordingly, when user wants to place things, he/she can just pull the handle 73 to pull out the drawer 70, and the things can be stored in the accommodating space 75. On the other hand, the drawer 70 would not occupy the space of the current environment after moving back.

Based on the spirit of the present invention, the structure of the electric bed frame 1 can be modified. For example, the two slidingly connecting portions 40 can be disposed at any position (such as the thigh rack 33, the back rack 31, and etc.) of the two movable racks 30 or the fixed rack 20. The connecting manner between the two slidingly connecting portions 40 and the drawer 70 is not limited to using the two slide rails 80. For example, each of the slidingly connecting portions 40 has a rail (not shown) for slidably connecting side fringes 77 of two sides of the body 71 of the drawer 70, so that the drawer 70 is movable along the two rails. The structure of the connecting member 41 can be modified. For example, the bottom plate 47 can be omitted. Alternatively the connecting member 41 is a set of bolt and nut which can directly connect the fixed member 81 of the slide rail 80 with the fixed rack 20 or the two movable racks 30. The fixed member 81 of the two slide rails 80 can be welded on the fixed rack 20 or the two movable racks 30, and those connecting members 41 can be omitted. The bottom plates 47 may support the bottom sides of the fixed members 81 of the two slide rails 80. Each of the slidingly connecting portions 40 may extend integrally from the fixed rack 20 or the two movable racks 30.
